learn me some welding

[Ridr4lfe96]

I talked to a professor at school today about possibly doing a special independent study course in welding. We have a TIG, MIG, and arc welder along with a plasma cutter. Does anyone have any suggestions on topics to cover in the course? He said if i came up with a general syllabus he would help me go through with it. I was thinking various materials and joint designs/positions with each welding process along with different stick electrodes. Basically im just looking for ideas on different things that can be done to learn more about welding in various situations. Thank you in advance

OK, how about the Pro's and Con's of each process, the applications best suited for each process, the history and development of each process. The joint designs and positions would be the same, while the materials could be specific to a process. Just tossing some things out......:drinkup:---- John

im sorry that i forgot to mention it would be more of a practical application/lab type class

Well fer starters Mig & Tig are Arc welders:drinkup:


use 'lectric arc they do

haha arent we hilarious?!?!?! lol

If you're in the educational arena, why do you create a subject heading
'Learn me some welding', that implies illiteracy?

Impressions do count!

This forum is seen by thousands to tens of thousands (or more)--world wide;
and I dare say that many of them have a better grasp of basic English;
as a second language-- than what your subject line implies.

I go to school out in the boonies. im surrounded by hillbillies. we joke about redneck accents and redneck ways of talking. if that offends someone im sorry

I was thinking it was a joke when I saw the title. But your idea sounds as though it could help kids learn something about the trades and there is always a need of younger people in these kinds of jobs.

No, don't change. California is already F&%Ked up enough. Stick to what works for you!!!:D My son has one of the most overpaid, least competent, over-full of herself school counselors I have ever met. She hasn't learnt nuthin' ......nothin' useful for the outside world at least. Thank God she is a state employee, otherwise, she'd be downright dangerous.
As for subject matter, the types of welding, and their basic functions would be good. Show examples of the work, pics and written. For instance, stick welding is the most common in the field heavy fabrication method of welding. The reasons are portability, ease of application, superior speed, minimal surface preperation, most versatile welding for outdoor applications. Mig welding in its' many forms...there are about 4 that come to mind, cover from super heavy duty production (Sub Arc,) and down to common GMAW for mass production. GTAW (Tig) for special production, aircraft, many racing and exotic alloy applications. There is no shortage of info here and online, and plenty of books and articles to gain reference from. And, in the end, you can make samples of much of it yourself, and if you beg just right, you could get a couple samples of weld process' you have no access to from members here.

idacal, unless im missing your sarcasm, i thank you for finally giving something constructive. i hope to help myself, along with some other students. learn more about welding processes. if anyone else has anything that would help me do this please share

Dave,

Since his post is rather well written, the Title "Learn me some welding" is rather humorous.

thank you broccoli

Another topic that is typically not covered very well is manufacturing processes. A brief explanation of how products are made. An explanation of the rolling process, cast, DOM, forge, etc,etc and the associated difficulties in joining these. Material types with pros and cons. Matching filler metals, for tensile and alloy. Basic mechanical testing that one can perform in a weld shop. Troubleshooting, in regard to evaluation of mechanical testing. It is very beneficial to be able to make a sample, test it, and then to make adjustments accordingly.

Are there any other testing methods I am unaware of? Obviously xray and similar tests but I do not have access to such facilities. I am not too familiar with testing procedures but I have seen pictures of welds that have been cross sectioned and marked with some sort of dye to show penetration? Does anyone have any information on this?

How about briefly touching on some of the related skills like simple math for measurements, social skills for business dealings, etc. I'm not talking indepth stuff, maybe just 30 minutes to touch upon other skill areas that need to be considered IF the student has a desire to open a business. Too many votech type schools are all about the technical theory, and not enough real world knowledge.

Those are examples of non destructive testing (NDT). Mechanical testing is destructive testing. Try a search on bend testing, fillet weld break test, and Macro-etch test. Mechanical testing take much less skill and investment. PT or penetrant testing is a form of NDT that is relatively cheap and easy to learn. It has 3 types of aerosol cans with directions on the can. Although a little more research is suggested for it's use.
